This video explores the Roth Haenel Model 1899, a semiautomatic sporting rifle developed by Georg Roth and Karel Krnka. Marketed by Haenel, the rifle featured a long recoil, rotating bolt design and was chambered for the 8x45mm cartridge. The description highlights the rifle's high price ($150 around 1900-1905) as a likely reason for its lack of commercial success, especially when compared to much cheaper bolt-action rifles and shotguns. The video also touches upon the question of whether it was the first commercial sporting semiautomatic rifle available, noting its contemporary status with early Remington and Winchester offerings.
This video explores the Roth-Theodorovic Prototype Pistol, a rare firearm developed in Austria. The pistol's lineage traces back to Georg Roth's company, which acquired the patent from inventor Wasa Theodorovic and had it developed by engineer Karel Krnka. Approximately 80 of these pistols were produced, with each exhibiting unique developmental improvements. This particular example, serial number 77, showcases a refined fire control system with single/double action and a decocker, along with a non-factory grip safety patented by Tambour and installed by a contemporary gunsmith. The video also references related Roth-Steyr models and Frommer pistols, highlighting the design's influence.
This video provides an in-depth analysis of the rare Roth-Sauer automatic pistol, designed by Karel Krnka and manufactured by J.P. Sauer & Sohn. It highlights the pistol's complex long-recoil action, where the bolt and barrel remain locked throughout the cycle. The firing mechanism is noted for its similarity to later designs like the Roth-Steyr 1907 and modern striker-fired pistols such as Glocks, featuring a striker tensioned to half-cock and fully cocked by the trigger pull. The video also discusses the specific 7.65mm Roth-Sauer cartridge, its dimensions, and its similarity to the short 7.65mm Frommer cartridge, with which Roth was also involved. The design is described as being significantly ahead of its time.
